Electrogenerated chemiluminescence resonance energy transfer between ZnGa2O4/g-C3N4 and gold nanoparticles/graphene and its application in the detection of thrombin

A label-free ECL sensor for thrombin was fabricated based on ECL resonance energy transfer occurred between ZnGa₂O₄/g-C₃N₄ and AuNP/GR nanocomposites, which revealed a new role of spinel-type semiconductor oxides in the fabrication of ECL sensors.
